The mobile terminal 100 also includes a display 151 that visuallydisplays information associated with the mobile terminal 100. Forinstance, if the mobile terminal 100 is operating in a phone call mode,the display 151 will generally provide a user interface (UI) orgraphical user interface (GUI) which includes information associatedwith placing, conducting, and terminating a phone call. As anotherexample, if the mobile terminal 100 is in a video call mode or aphotographing mode, the display 151 may additionally or alternativelydisplay images which are associated with these modes or the UI and GUI.

Further, the display 151 may be implemented using at least one ofdisplay technologies including, for example, a liquid crystal display(LCD), a thin film transistor-liquid crystal display (TFT-LCD), anorganic light-emitting diode display (OLED), a flexible display and athree-dimensional display.

Under this configuration, a user can view anobject positioned at a rear side of a terminal body through the display151 of the terminal body.

The display 151 may be implemented in two or more in number according toa configured aspect of the mobile terminal 100. For instance, aplurality of the displays 151 may be arranged on one surface in aspacing manner or in an integrated manner, or may be arranged ondifferent surfaces.

Here, if the display 151 and a touch sensitive sensor (referred to as atouch sensor) have a layered structure therebetween, the structure maybe referred to as a touch screen. The display 151 may be used as aninput device rather than an output device. The touch sensor may beimplemented as a touch film, a touch sheet, a touch pad, and the like.

The touch sensor may be configured to convert changes of a pressureapplied to a specific part of the display 151, or a capacitanceoccurring from a specific part of the display 151, into electric inputsignals. Also, the touch sensor may be configured to sense not only atouched position and a touched area, but also a touch pressure. Whentouch inputs are sensed by the touch sensor, corresponding signals aretransmitted to a touch controller (not shown). The touch controllerprocesses the received signals, and then transmits corresponding data tothe controller 180. Accordingly, the controller 180 may sense whichregion of the display 151 has been touched.

The proximity sensor 141 may be arranged at an inner region of themobile terminal 100 covered by the touch screen, or near the touchscreen. The proximity sensor 141 indicates a sensor to sense presence orabsence of an object approaching to a surface to be sensed, or an objectdisposed near a surface to be sensed, by using an electromagnetic fieldor infrared rays without a mechanical contact. The proximity sensor 141has a longer lifespan and a more enhanced utilization degree than acontact sensor.

When thetouch screen is implemented as a capacitance type, proximity of apointer to the touch screen is sensed by changes of an electromagneticfield. In this case, the touch screen (touch sensor) may be categorizedinto a proximity sensor.

Hereinafter, a status that the pointer is positioned to be proximateonto the touch screen without contact will be referred to as ‘proximitytouch’, whereas a status that the pointer substantially comes in contactwith the touch screen will be referred to as ‘contact touch’. Thepointer in a status of ‘proximity touch’ is positioned so as to bevertical with respect to the touch screen.

The proximity sensor 141 senses proximity touch, and proximity touchpatterns (e.g., distance, direction, speed, time, position, movingstatus, etc.). Information relating to the sensed proximity touch, andthe sensed proximity touch patterns may be output onto the touch screen.

The audio output module 152 may output audio data received from thewireless communication unit 110 or stored in the memory 160, in acall-receiving mode, a call-placing mode, a recording mode, a voicerecognition mode, a broadcast reception mode, and so on.

The audio output module 152 mayinclude a receiver, a speaker, a buzzer, and so on.

The alarm 153 outputs signals notifying occurrence of events from themobile terminal 100. The events occurring from the mobile terminal 100may include call signal reception, message reception, key signal input,touch input, and so on. The alarm 153 may output not only video or audiosignals, but also other types of signals such as signals notifyingoccurrence of events in a vibration manner. When call signals ormessages are received, the alarm 153 may implement the mobile terminal100 to vibrate through a vibration means in order to notify thereception. When key signals are input, the alarm 153 may implement themobile terminal 100 to vibrate through a vibration means as a feedbackto the input. A user can recognize occurrence of events through thevibration of the mobile terminal 100. Signals notifying occurrence ofevents may be output through the display 151 or the audio output module152. The display 151 and the audio output module 152 may be categorizedinto a part of the alarm 153.

The haptic module 154 generates various tactile effects. Arepresentative example of the tactile effects generated by the hapticmodule 154 includes vibration.

Also, when the mobileterminal enters a preset region of the arrival point while displayingthe road guidance information on the LCD 211, the navigation apparatus300 applied to the telematics terminal 200 according to the presentinvention checks whether the arrival point is the ultimate destination,and then sets the ultimate destination according to the result of thechecking. Afterwards, the navigation apparatus 300 generates new routerelated information based upon the set ultimate destination and thecurrent position of the telematics terminal 200 and sends the generatednew route related information to a particular terminal, such that thesent new route related information is displayed on the particularterminal. Also, the navigation apparatus 300 can send positioninformation related to the set ultimate destination to the particularterminal, and generates a new route based upon the sent positioninformation and/or position information relating to the particularterminal, so as to display the newly generated route related informationon the particular terminal.

Here, functions of the navigation apparatus 300 according to theembodiment of the present invention will be executed by the navigationapparatus 300 itself or by the central processing unit 222 of thetelematics terminal 200.

Hereinafter, the navigation apparatus 300 will be explained in moredetail, with reference to FIG. 3, under an assumption that thenavigation apparatus 300 is applied to the telematics terminal 200.Here, the navigation apparatus 300 of the present invention may beapplied not only to the telematics terminal 200, but also to the mobileterminal 100.

FIG. 3 is a block diagram showing a structure of the navigationapparatus according to the present invention.

As shown in FIG. 3, the contents navigation apparatus 300 comprises aGPS receiver 301, a Dead-Reckoning (DR) sensor 302, an input unit 303, amap matching unit 304, a storage unit 305, a display unit 306, a voiceoutput unit 307, a controller 308, and a communication unit 309.

The GPS receiver 301 receives a GPS signal from a satellite, generatesin real time first position data of the navigation apparatus 300(assumed to be the same position to the telematics terminal 200 or themobile terminal 100) based upon latitude and longitude coordinatesincluded in the received GPS signal, and output the generated firstposition data to the map matching unit 304. Here, the first positiondata is defined as a current position (or current position data) of thenavigation apparatus 300. The position information can be receivedthrough a Wi-Fi or Wibro communication as well as the GPS receiver 301.

The signal received through the GPS receiver 301 may provide theposition information relating to the terminal to the navigationapparatus 300 by using wireless communications, such as IEEE 802.11 as awireless network standard for a wireless LAN including wireless LAN,part of Infrared Data Associations (IrDA) and the like, proposed byInstitute of Electrical and Electronics Engineers (IEEE), IEEE 802.15 asa standard for a wireless Personal Area Network (PAN) includingBLUETOOTH, Ultra-WideBand (UWB), Zigbee and the like, IEEE 802.16 as astandard for a wireless Metropolitan Area Network (MAN)(BroadbandWireless Access, BWA) including Fixed Wireless Access (FWA) and thelike, and IEEE 802.20 as a mobile internet standard for a wireless MAN(Mobile Broadband Wireless Access, MBWA) including Wireless Broadband(Wibro), World Interoperability for Microwave Access (WiMAX) and thelike.

The DR sensor 302 calculates a running direction and running speed of avehicle when the terminal (i.e., navigation apparatus 300) is built inthe corresponding vehicle, generates second position data based upon thecalculated running direction of the vehicle and the running speedthereof, and outputs the generated second position data to the mapmatching unit 304.

Here, a technology of generating a presumptive position of thenavigation apparatus (or the mobile terminal or vehicle) based upon thefirst position data generated by the GPS receiver 301 and the secondposition data generated by the DR sensor 302 is well known to thoseskilled in the art, and thus a detailed description thereof will beomitted.

The input unit 303 receives a button input by a user or a command orcontrol signal in cooperation with a manipulation, such astouching/scrolling a display screen.

The input unit 303 may also be configured for a user to select hisdesired function or input information, and may be configured as variousdevices, such as a keypad, a touch screen, a jog wheel, a microphone andthe like.

The map matching unit 304 generates a presumptive vehicle position basedupon the first and second position data, and reads out map datacorresponding to a running route from the storage unit 305.

The map matching unit 304 also matches the presumptive vehicle positionwith links (roads) included in the map data, and outputs the matched mapinformation (i.e., the map matching result) to the controller 308. Forinstance, the map matching unit 304 generates the presumptive vehicleposition based upon the first and second position data, and then matchesthe generated presumptive vehicle position with the links included inthe map data stored in the storage unit 305 in a sequential manner, soas to output the matched map information (i.e., the map matching result)to the controller 308.

The map matching unit 304 also outputs to the controller 308 a roadattribute information, such as a single story road or a multi storyroad, which is included in the matched map information (i.e., the mapmatching result).

Such functions of the map matching unit 304 can be implemented by thecontroller 308.

The storage unit 305 stores map data.

The storage unit 305 also stores various types of information, includinga variety of menu screens, point of interest (POI), information relatedto each function according to a specific position of the map data andthe like.

The storage unit 305 also stores a variety of user interfaces (UIs)and/or graphic user interfaces (GUIs).

In addition, the storage unit 305 stores data and programs required forthe operation of the navigation apparatus 300.

The display unit 306 displays graphic information (or a road guidancemap) included in the road guidance information generated by thecontroller 308. Here, the display unit 306 can be a touch screen.

The display unit 306 may display various contents such as different menuscreens and road guidance information using UIs and/or GUIs stored inthe storage unit 305. Here, the contents displayed on the display unit306 may include menu screens having various texts or image data (mapdata or each kind of information data), icons, list menus and comboboxes.

The voice output unit 307 outputs voice information included in the roadguidance information (or voice message for the road guidanceinformation) generated by the controller 308. Here, the voice outputunit 307 may be implemented as a speaker.

The controller 308 generates road guidance information based upon thematched map information, and then outputs the generated road guidanceinformation to the display unit 306 and the voice output unit 307. Here,the display unit 306 displays the road guidance information.

Also, the controller 308 receives real-time traffic information from aninformation providing center 500 connected thereto via a wired/wirelesscommunication network 400. The received real-time traffic information isused upon the generation of the road guidance information.

The controller 308 may be connected to a call center 600 via thecommunication unit 309, so as to execute a call communication or allowstransmission/reception of information between the navigation apparatus300 and the call center 600. Here, the communication unit 309 may beimplemented as a hands-free module having a BLUETOOTH function employinga short-range wireless communication technique.

The controller 308 retrieves a route (path) based upon start point andarrival point or upon an arrival point, and outputs the retrieval resultto the display unit 306.

Also, when the current position of the navigation apparatus 300 is nearthe arrival point upon the traveling, then the controller 308 may checkwhether or not the arrival point is the ultimate destination. And, thecontroller 308 may generate a new route between the current position ofthe navigation apparatus 300 and the ultimate destination according tothe checked result, so as to send to a particular terminal.

In addition, when the current position of the navigation apparatus 300is near the arrival point during the driving, then the controller 308may check whether or not the arrival point is the ultimate destination,and send to the particular terminal either position information (orposition related information) related to the ultimate destination orposition (related) information related to both the ultimate destinationand the current position of the navigation apparatus 300 according tothe checked result.

When the current position of the navigation apparatus 300 is near thearrival point during the traveling, then the controller 308 generates anew route based upon position information related to the arrival point,so as to send the newly generated route to a particular terminal or sendthe position information to the particular terminal. Here, the positioninformation may include the arrival point, or include the arrival pointand the current position of the navigation apparatus 300.

Also, the functions of the map matching unit304 and the controller 308 may be executed by the controller 180 of themobile terminal 100. Alternatively, the map matching unit 304 and thecontroller 308 may be implemented as an independent module in the mobileterminal 100.

Hereinafter, a navigation method according to the present invention willbe described in detail with reference to FIGS. 1 to 3.

FIG. 4 is a flowchart showing a navigation method in accordance with afirst embodiment of the present invention

First, the map matching unit 304 generates first position data and/orsecond position data based upon signals respectively received by the GPSreceiver 301 and/or the DR sensor 302, and generates a currentpresumptive position based upon the generated first and/or secondposition data. Afterwards, the map matching unit 304 reads out map datacorresponding to a running route from the storage unit 305. Here, therunning route refers to a route from a starting point to an arrivalpoint.

The map matching unit 304 then matches the presumptive position withlinks (roads) included in the map data, and outputs the matched mapinformation (i.e., map matching result) to the controller 308. Forexample, the map matching unit 304 generates the presumptive positionbased upon the first and second position data and then matches thegenerated presumptive position with the links within the map data storedin the storage unit 305 in a sequential manner, to thereafter output thematched map information (i.e., map matching result) to the controller308. Here, the matched map information (i.e., map matching result)corresponds to information generated by referring to preset userinformation, a road condition using Transport Protocol Expert Group(TPEG) information or the like, current status information of a vehicle(e.g., oil state (e.g., pressure/level/temperature), air pressure stateof tire, etc.) and the like.

Afterwards, the controller 308 generates road guidance information basedupon the matched map information, and outputs the road guidanceinformation to the display unit 306 and the voice output unit 307(S110).

The controller 308 then determines whether the navigation apparatus 300is currently positioned near the arrival point. Here, the determinationas to whether the navigation apparatus 300 is currently positioned nearthe arrival point is to determine whether or not the navigationapparatus 300 is currently positioned within a range (or a radius)preset based upon the arrival point.

As one example, assuming that the arrival point is ‘City Hall’ and thenavigation apparatus 300 enters (or is positioned) within a radius of500 m, as a preset range based upon the City Hall, the navigationapparatus 300 is determined to be near the arrival point, namely, theCity Hall (S120).

If the navigation apparatus 300 is determined to be near the arrivalpoint, then the navigation apparatus 300 checks whether the arrivalpoint is the ultimate destination. In one embodiment, checking whetherthe arrival point is the ultimate destination is implemented such that aGUI screen such as a pop-up window is used, as shown in FIG. 5, tooutput a message for inquiring whether the arrival point (or aninitially inputted arrival point) is the ultimate. In reply, the userselects an input value such as Yes' or ‘No’, responsive to the outputtedmessage. Accordingly, the navigation apparatus 300 confirms whether thearrival point is the ultimate destination based upon the input value(S130).

According to the check result, if the arrival point is the ultimatedestination, the controller 308 generates a new route between thecurrent position and the arrival point, and then sends informationrelating to the newly generated route to a particular terminal (S140).

On the other hand, if the arrival point is not the ultimate destinationaccording to the check result, the controller 308 receives the ultimatedestination from the user.

Afterwards, a new route is generated based upon the input ultimatedestination and the current position of the navigation apparatus 300,and then information related to the newly generated route is wirelesslysent to the particular terminal (S150). In another embodiment, theinformation related to the newly generated route is sent to theparticular terminal via a wired connection.

The particular terminal then outputs the information related to the newroute sent in the steps (S140 or S150) to via a corresponding terminaldisplay and/or voice output unit. Here, the sent information related tothe new route, as shown in FIG. 6, may be one of map data in a graphicformat (see FIG. 6(a)), abbreviated map data in a graphic format (seeFIG. 6(b)), data in a turn-by-turn list format (see FIG. 6(c)), data ina text format (see FIG. 6(d)), data in an animation format, and data ina multimedia format providing video information about a route (an actualroute). Here, upon displaying the data, the particular terminal canreproduce the video information corresponding to a straight sectionincluded in the route at a speed faster than a typical reproductionspeed, and reproduce the video information corresponding to a curvedsection included in the route at a speed slower than the typicalreproduction speed. The map data in the graphic format shown in FIG.6(a) indicates a new route 700 generated between the ultimatedestination (i.e., point B) and the current position of the navigationapparatus 300 (point C) based upon the map data displayed at thenavigation apparatus 300 or terminal (i.e., point C). Also, theabbreviated map data in the graphic format shown in FIG. 6(b) indicatesa new route 700 generated in the limited (or abbreviated) map databetween the ultimate destination (i.e., point B) and the currentposition of the navigation apparatus 300 (i.e., point C) in the map datashown in FIG. 6(a). The data in the turn-by-turn list format shown inFIG. 6(c) indicates a route from the current position (i.e., point C) ofthe navigation apparatus 300 to the ultimate destination (i.e., point B)in the turn-by-turn list format. Also, the data in the text format shownin FIG. 6(d) indicates a route from the current position (i.e., point C)of the navigation apparatus 300 to the ultimate destination (i.e., pointB) in text format. In one embodiment, voice data corresponding to thedata in the text format can be included in the information related tothe new route together with the data in the text format.

The particular terminal may be one of mobile phone, portable terminal,smart phone, notebook computer, digital broadcasting terminal, personaldigital assistants (PDA), portable multimedia player (PMP), WiBroterminal, telematics terminal, wireless terminal and navigation (vehiclenavigation apparatus).

Also, the information (or data) transmission between the navigationapparatus 300 and the particular terminal may be implemented usingBLUETOOTH, IrDA, UWB, ZigBee, wired/wireless universal serial bus (USB)(S160).

FIG. 7 is a flowchart showing a navigation method in accordance with asecond embodiment of the present invention.

First, the map matching unit 304 generates first position data and/orsecond position data based upon signals respectively received by the GPSreceiver 301 and/or the DR sensor 302, and generates a currentpresumptive position based upon the generated first and/or secondposition data. Afterwards, the map matching unit 304 reads out map datacorresponding to a running route from the storage unit 305. Here, therunning route refers to a route from a starting point to an arrivalpoint.

The map matching unit 304 then matches the presumptive position withlinks (roads) included in the map data, and outputs the matched mapinformation (map matching result) to the controller 308. For example,the map matching unit 304 generates the presumptive position based uponthe first and second position data and then matches the generatedpresumptive position with the links within the map data stored in thestorage unit 305 in a sequential manner, to thereafter output thematched map information (map matching result) to the controller 308.Here, the matched map information (map matching result) corresponds toinformation generated by referring to preset user information, a roadcondition using Transport Protocol Expert Group (TPEG) information orthe like, a current status information of a vehicle (e.g., oil state,air pressure state of tire, etc.) and the like.

Afterwards, the controller 308 generates road guidance information basedupon the matched map information, and outputs the road guidanceinformation to the display unit 306 and the voice output unit 307(S210).

The controller 308 then determines whether the navigation apparatus 300is currently positioned near the arrival point. Here, the determinationas to whether the navigation apparatus 300 is currently positioned nearthe arrival point is to determine whether or not the navigationapparatus 300 is currently positioned within a range (or a radius)preset based upon the arrival point (S220).

If the navigation apparatus 300 is determined to be near the arrivalpoint, then the navigation apparatus 300 checks whether the arrivalpoint is the ultimate destination. In one embodiment, checking whetherthe arrival point is the ultimate destination is implemented such that aGUI screen such as a pop-up window is used, as shown in FIG. 5, tooutput a message for inquiring whether the arrival point (or aninitially inputted arrival point) is the ultimate destination. In reply,the user selects an input value such as ‘Yes’ or ‘No’, responsive to theoutputted message. Accordingly, the navigation apparatus 300 confirmswhether the arrival point is the ultimate destination based upon theinput value (S230).

If the arrival point is the ultimate destination according to the checkresult, the position information is sent to a particular terminal via awireless or wired connection. Here, the sent position information (orposition related information) may be either information relating to theultimate destination or information relating to the ultimate destinationand the current position of the navigation apparatus 300 (S240).

If the arrival point is not the ultimate destination according to thecheck result, the ultimate destination is input by a user.

Afterwards, such position information relating to the input ultimatedestination or position information related to the input ultimatedestination and the current position of the navigation apparatus 300 issent to the particular terminal (S250).

The particular terminal then generates a new route based upon theposition information sent in the step (S240 or S250), and outputs thenewly generated route to its display and/or voice output unit. Here, thesent information related to the new route, as shown in FIG. 6, may beone of map data in a graphic format (see FIG. 6(a)), abbreviated mapdata in a graphic format (see FIG. 6(b)), data in a turn-by-turn listformat (see FIG. 6(c)), data in a text format (see FIG. 6(d)), data inan animation format, and data in a multimedia format providing videoinformation about a route (an actual route). Here, upon displaying thedata, the particular terminal can reproduce the video informationcorresponding to a straight section included in the route at a speedfaster than a typical reproduction speed, and reproduce the videoinformation corresponding to a curved section included in the route at aspeed slower than the typical reproduction speed.

For instance, when the arrival point is the ultimate destination, theposition information sent from the navigation apparatus 300 to theparticular terminal denotes the position information relating to thearrival point, or the position information relating both to the arrivalpoint and to the current position of the navigation apparatus 300. Ifthe position information includes only the information relating to thearrival point, the particular terminal generates a new route based uponthe information relating to the arrival point and current positioninformation related to the particular terminal and then outputs thenewly generated route. That is, when the information relating to thearrival point is only sent, the particular terminal generates a newroute based upon the current position information thereof and theinformation relating to the arrival point and then outputs the newroute. Also, when the position information includes the informationrelating to the arrival point and the current position informationrelated to the navigation apparatus 300, the particular terminal thengenerates a new route based upon the information relating to the arrivalpoint and the current position information related to the navigationapparatus 300 and/or the current position information related to theparticular terminal itself so as to output the newly generated route.Here, the current position of the particular terminal denotes positiondata obtained by using position data generated based upon signalsreceived via the GPS receiver and/or the DR sensor provided in theparticular terminal.

As another example, when the arrival point is not the ultimatedestination, the position information sent from the navigation apparatus300 to the particular terminal may be either information related to theultimate destination input by the user, or position informationincluding the information related to the ultimate destination input bythe user and the current position information related to the navigationapparatus 300. When the position information includes only theinformation related to the ultimate destination input by the user, theparticular terminal then generates a new route based upon theinformation related to the ultimate destination input by the user andcurrent position information related to the particular terminal itselfand outputs the newly generated route. When the position informationincludes the information related to the ultimate destination input bythe user and the current position information of the navigationapparatus 300, the particular terminal generates a new route based uponthe information related to the ultimate destination input by the userand the current position information related to the navigation apparatus300 and/or the current position information related to the particularterminal itself, and then outputs the newly generated route (S260).

FIG. 8 is a flowchart showing a navigation method in accordance with athird embodiment of the present invention.

First, the map matching unit 304 generates first position data and/orsecond position data based upon signals respectively received via theGPS receiver 301 and/or the DR sensor 302, and generates a currentpresumptive position based upon the generated first and/or secondposition data. Afterwards, the map matching unit 304 reads out map datacorresponding to a running route from the storage unit 305. Here, therunning route refers to a route from a starting point to an arrivalpoint.

The map matching unit 304 matches the presumptive position with links(roads) included in the map data, and outputs the matched mapinformation (map matching result) to the controller 308. For example,the map matching unit 304 generates the presumptive position based uponthe first and second position data and then matches the generatedpresumptive position with the links within the map data stored in thestorage unit 305 in a sequential manner, to thereafter output thematched map information (map matching result) to the controller 308.Here, the matched map information (map matching result) corresponds toinformation generated by referring to preset user information, a roadcondition using Transport Protocol Expert Group (TPEG) information orthe like, a current status information of a vehicle (e.g., oil state,air pressure state of tire, etc.) and the like.

Afterwards, the controller 308 generates road guidance information basedupon the matched map information, and outputs the road guidanceinformation to the display unit 306 and the voice output unit 307(S310).

The controller 308 then determines whether the navigation apparatus 300is currently positioned near the arrival point. Here, the determinationas to whether the navigation apparatus 300 is currently positioned nearthe arrival point is to determine whether or not the navigationapparatus 300 is currently positioned within a range (or a radius)preset based upon the arrival point (S320).

According to the check result, if the navigation apparatus 300 iscurrently positioned near the arrival point, the controller 308generates a new route between the current position of the navigationapparatus 300 and the arrival point, and then sends information relatingto the newly generated route to a particular terminal (S330).

The particular terminal then outputs the information related to the newroute to its display and/or voice output unit. Here, the sentinformation related to the new route, as shown in FIG. 6, may be one ofmap data in a graphic format (see FIG. 6(a)), abbreviated map data in agraphic format (see FIG. 6(b)), data in a turn-by-turn list format (seeFIG. 6(c)), data in a text format (see FIG. 6(d)), data in an animationformat, and data in a multimedia format providing video informationabout a route (an actual route). Here, upon displaying the data, theparticular terminal can reproduce the video information corresponding toa straight section included in the route at a speed faster than atypical reproduction speed, and reproduce the video informationcorresponding to a curved section included in the route at a speedslower than the typical reproduction speed (S340).

FIG. 9 is a flowchart showing a navigation method in accordance with afourth embodiment of the present invention.

First, the map matching unit 304 generates first position data and/orsecond position data based upon signals respectively received via theGPS receiver 301 and/or the DR sensor 302, and generates a currentpresumptive position based upon the generated first and/or secondposition data. Afterwards, the map matching unit 304 reads out map datacorresponding to a running route from the storage unit 305. Here, therunning route refers to a route from a starting point to an arrivalpoint.

The map matching unit 304 then matches the presumptive position withlinks (roads) included in the map data, and outputs the matched mapinformation (map matching result) to the controller 308. For example,the map matching unit 304 generates the presumptive position based uponthe first and second position data and then matches the generatedpresumptive position with the links within the map data stored in thestorage unit 305 in a sequential manner, to thereafter output thematched map information (map matching result) to the controller 308.Here, the matched map information (map matching result) corresponds toinformation generated by referring to preset user information, a roadcondition using Transport Protocol Expert Group (TPEG) information orthe like, a current status information of a vehicle (e.g., oil state,air pressure state of tire, etc.) and the like.

Afterwards, the controller 308 generates road guidance information basedupon the matched map information, and outputs the road guidanceinformation to the display unit 306 and the voice output unit 307(S410).

The controller 308 then determines whether the navigation apparatus 300is currently positioned near the arrival point. Here, the determinationas to whether the navigation apparatus 300 is currently positioned nearthe arrival point is to determine whether or not the navigationapparatus 300 is currently positioned within a range (or a radius)preset based upon the arrival point (S420).

If the navigation apparatus 300 is determined to be near the arrivalpoint, the position information is sent to a particular terminal. Here,the sent position information may be either information related to thearrival point, or position information including the information relatedto the arrival point and the current position information related to thenavigation apparatus 300 (S430).

Then, the particular terminal generates a new route based upon the sentposition information and outputs the newly generated route on a displayand/or a voice output unit thereof. Here, the information related to thenewly generated route, as shown in FIG. 6, may be one of map data in agraphic format (see FIG. 6(a)), abbreviated map data in a graphic format(see FIG. 6(b)), data in a turn-by-turn list format (see FIG. 6(c)),data in a text format (see FIG. 6(d)), data in an animation format, anddata in a multimedia format providing video information about a route(an actual route). Here, upon displaying the data, the particularterminal can reproduce the video information corresponding to a straightsection included in the route at a speed faster than a typicalreproduction speed, and reproduce the video information corresponding toa curved section included in the route at a speed slower than thetypical reproduction speed.

For instance, when the sent position information includes only theinformation related to the arrival point, the particular terminalgenerates a new route based upon the current position informationthereof and outputs the newly generated route. Also, when the sentposition information includes both the information related to thearrival point and the current position information related to thenavigation apparatus 300, the particular terminal generates a new routebased upon the information related to the arrival point and the currentposition information related to the navigation apparatus 300 and/or thecurrent position information of the particular terminal itself so as tooutput the newly generated route. Here, the current position of theparticular terminal denotes position data obtained by using positiondata generated based upon signals received via the GPS receiver and/orthe DR sensor provided in the particular terminal (S440).

As such, in the navigation methods shown in FIGS. 4 to 9, the particularterminal and/or the navigation apparatus 300 are/is provided with commonor interoperable software (or program) to output route information usingthe software, or provided with different types of software to output theroute information using the corresponding software.

For example, in case where the navigation apparatus 300 and theparticular terminal have the same software, information related to thenewly generated route by the navigation apparatus 300 can be usedwithout processing or changes. That is, the screen of FIG. 6(a)displayed on the navigation apparatus 300 may equally be displayed evenon the particular terminal using the same software.

In addition, in case where the navigation apparatus 300 and theparticular terminal have the same software or different software, asshown in FIGS. 6(b) to 6(d), the information related to the newlygenerated route by the navigation apparatus 300 may be one of map datain an image file format (see FIG. 6(b)) turn-by-turn list format (or animage file in the form of an outline (see FIG. 6(c)), which is routefocused information, or data in the text format (see FIG. 6(d)), allbased upon the current position of the navigation apparatus 300 and thearrival point. As such, such data in the image file format, theturn-by-turn list format or the text format can be sent to theparticular terminal, and the sent data can be output using the softwareprovided in the particular terminal.

Also, in case where the navigation apparatus 300 and the particularterminal have the same software or different software, upon receivingposition information and generating new route related information basedon the position information in the particular terminal, the newlygenerated route related information may be one of the map data in theimage file format (or an image file in the form of an outline), the datain the turn-by-turn list format, or the data in the text format.

FIG. 10 is a flowchart showing a navigation method in accordance with afifth embodiment of the present invention.

First, a first map matching unit provided in a first terminal generatesfirst position data and/or second position data based upon signalsrespectively received via a first GPS receiver and/or a first DR sensordisposed in the first terminal, and calculates a current presumptiveposition based upon the first and/or second position data. Afterwards,the first map matching unit reads out map data corresponding to arunning route from a first storage unit disposed in the first terminal.Here, the running route denotes a traveling route from a starting pointto an arrival point.

The first map matching unit matches the presumptive position with links(roads) included in the map data, and outputs the matched mapinformation (i.e., the map matching result) to a first controllerdisposed in the first terminal. For example, the first map matching unitgenerates the presumptive position based upon the first and second data,and matches the generated presumptive position with the links within themap data stored in the first storage unit in a sequential manner, so asto output the matched map information (i.e., the map matching result) tothe first controller. Here, the matched map information (i.e., the mapmatching result) corresponds to information generated by referring topreset user information, a road condition using Transport ProtocolExpert Group (TPEG) information or the like, current status informationof a vehicle (e.g., oil state, air pressure state of tire, etc.) and thelike.

Afterwards, the first controller generates road guidance informationbased upon the matched map information and outputs the generated roadguidance information to a first display and a first voice output unitdisposed in the first terminal.

The first controller determines whether the first terminal is currentlypositioned near the arrival point. Here, the determination as to whetherthe first terminal is currently positioned near the arrival point is todetermine whether or not the first terminal is currently positionedwithin a range (or a radius) preset based upon the arrival point (S510).

If the first terminal is positioned near the arrival point according tothe determination, the first controller generates a new route betweenthe current position of the first terminal and the arrival point, andsends information related to the newly generated route to an informationproviding center 500 and/or a call center 600.

If the first terminal is positioned near the arrival point according tothe determination, the first controller may send, to the informationproviding center 500 and/or the call center 600, information related tothe arrival point (or an ultimate destination) or position informationrelated both to the arrival point and to the current position of thefirst terminal.

In addition, if the first terminal is positioned near the arrival point,the first controller checks whether the arrival point is the ultimatedestination. According to the checked result, if the arrival point isnot the ultimate destination, the first controller may receive a newultimate destination so as to use the input ultimate destination (S520).

Afterwards, a second terminal requests, from the information providingcenter 500 and/or the call center 600, the transmission of the sentnewly generated route related information or the position information.Here, the second terminal can be authenticated so as to determinewhether the corresponding information (i.e., the newly generated routerelated information or the position information) is enabled to be sentfrom the information providing center 500 and/or the call center 600 tothe second terminal (S530).

The information providing center 500 and/or the call center 600 thensends to the second terminal the newly generated route relatedinformation or the position information received from the firstterminal, responsive to the request for the transmission of theinformation by the second terminal (S540).

Then, the second terminal executes certain processes for the receivedroute related information or the position information, and then outputsthe result of the execution to its second display and/or second voiceoutput unit.

That is, when the received information is the new route relatedinformation, then the second terminal outputs the received new routerelated information to the second display and/or the second voice outputunit thereof. Here, the new route related information, as shown in FIG.6, may be one of map data in a graphic format (see FIG. 6(a)),abbreviated map data in a graphic format (see FIG. 6(b)), data in aturn-by-turn list format (see FIG. 6(c)), data in a text format (seeFIG. 6(d)), data in an animation format, and data in a multimedia formatproviding video information about a route (an actual route). Here, upondisplaying the data, the particular terminal can reproduce the videoinformation corresponding to a straight section included in the route ata speed faster than a typical reproduction speed, and reproduce thevideo information corresponding to a curved section included in theroute at a speed slower than the typical reproduction speed.

Also, when the received information is the position information, thenthe second terminal generates a new route based upon the positioninformation related to the arrival point, or upon the positioninformation related to the arrival point and the current position of thefirst terminal. That is, when the position information includes theinformation related to the arrival point, the second terminal newlygenerates a first route based upon the arrival point and its position,and then outputs the newly generated first route to the second displayand/or the second voice output unit. Also, when the position informationincludes both the arrival point and the current position of the firstterminal, the second terminal newly generates a second route based uponthe arrival point and the current position of the first terminal, andthen outputs the newly generated second route to the second displayand/or the second voice output unit (S550).

As such, the information providing center 500 and/or the call center 600can be configured to serve as an intermediary or a server between thefirst and second terminals. Also, the interconnection among the firstand second terminals and the information providing center 500 (or thecall center 600) can be implemented using a wired/wireless communicationtechnology.

The first and second mobile terminals described above may be implementedas various forms. Examples of the forms may include portable terminals,smart phones, notebook computers, digital broadcasting terminals,Personal Digital Assistants (PDA), Portable Multimedia Players (PMP),WiBro terminals, telematics terminals, wireless terminals, navigations(mobile vehicle navigation apparatus), and the like.

In the navigation apparatus and method according to the above-describedembodiments of the present invention, the first and second terminalscooperate with each other so as to share information related to routeguidance, so as to enhance the convenience of use.

Also, in the navigation apparatus and method according to theabove-described embodiments of the present invention, the secondterminal is allowed to provide position information related to anarrival point which is currently being provided by the first terminal,such that the second terminal is allowed to generate information relatedto a new route according to such condition so as to provide to a user,thereby improving efficiency of the use due to the sharing ofinformation between the terminals.
